Newton-Raphson Method Calculator

Dear Students!

Do you wanna find square root of real valued function using online calculator?

Yes here it is @ easycalculation website.

You can calculate the square roots of a real valued function using Newton's Iteration method.

Newton-Raphson Method is a root finding iterative algorithm for computing equations numerically. It is also called as Newton's method or Newton's iteration. Simply enter the expression as input by following the rules and enter the value for variable x.

For example:
For (x^3)-2*x-5 & x=2; The square root of the expression is as follows:

x - ((x^3) - 2 * x - 5) / (3 * (x^2) - (2)) = 2.1

Hey guys...Make use of this useful website to Calculate Square root expression using Newton-Raphson Method Calculator from

Re: Newton-Raphson Method Calculator

Okay, but you are not solving a square root. That example is the first iteration to find the real root of x^3 - 2x - 5 = 0

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
